Hot Fudge Sauce

Soda fountains were a natural fit in drugstores because the skills of an old-time pharmacist, who actually manufactured medicine, translated seamlessly into the skills of a confectioner who concocted exotic syrups for sodas, phosphates, sundaes, and milkshakes.

Nowadays, most vintage soda fountains buy their syrups ready made. But there is one sweetshop treat that no one has yet been able to bottle or package so it tastes as good as a batch fresh off the stove: hot fudge sauce.
